Hi ,

• You can save as the rule in your screenshot into a new Name such as "cosmos-preview-panel" (as it is a Final Rule ) save it into your Application Ruleset  and can change the line 

 peekElem.text = "Preview"  to  peekElem.text = pega.u.d.fieldValuesList.get("Previewtext");

•  Create a Field value With Name "Previewtext" and add desired text into that..

• Save as "pz-cosmos-ui-scripts • script" Static Bundle Rule into your Ruleset and add the above creates js file replacing the "pz-cosmos-preview-panel.js"

Hope this Helps!!
